LITTLE ROCK (AP) — Authorities in Little Rock have upgraded a battery charge to murder after a homeless man who was attacked with a liquor bottle on July 30 died.

Little Rock police said Thursday that 51-year-old Donald Ray Jenkins was found with wounds that included an injury to the back of his head and taken to a hospital.

The victim told police he’d been struck on the head with a whiskey bottle.

Investigators arrested 43-year-old Thomas Daniel Trosper on a first-degree battery charge. Jenkins died after being taken off life support on Wednesday. Police say the charge against Trosper was upgraded to first-degree murder.

Trosper was being held at the Pulaski County Jail on Thursday. No bond had been set and it was unclear whether he had a lawyer.
